16. Sodium metal crystallizes in a cubic cell. From X-ray diffraction, the unit cell parameter was determined to be 4.29 A. If the density of the element is known to be 0.968 g/cm', how many atoms are present in each unit cell? a) Not enough intomation is given to calculate the value. (6) 2 (d) 4 17. A metal crystallizes in face-centered cubic lattice with a lattice parameter of4.20 A. The shortest atom to atom contact distance in the lattice is: a) 4.20 Å (b) 2.97 A ()2.42 A (d) 2.10 Å

    For ques 16 calculate using density formula...

    eduncle-logo-app

    d=ZM/a^3 Na

    eduncle-logo-app

    density is given...unit cell parameter is given
